Be it knownthat I, Dr. Josnr Somnssnnn, subject of the Emperor of Austria-.Hungary,

residing at Baden, near .Vienna,'Austria- Hungary, have invented. certain new and useful Improvements in Electric Capacitalowing is a Specification, and is a di s tative-inductive,

. of my application, Serial. N0. 5 93 ,890, filed November-23,1910. V I o This invention relates to an electric capacithat is to say an electrostatic-magnetic coupling, suitable for connecting the primary'andsecondary circuits of telegraphic and telephonic systems. The improved coupling possesses all'the advantages of capacitative and inductive coupling so that the energy supplied is transmitted out of the primary system-into thesecondary systemvboth theelectrical as Well as by the magnetic field. Acondenser forming one part of the coupling may be placed in the primary system and themethod of connection and "rangements' may be employed. Naturally arrangement is employed aninduction coil forming another part or":

the coupling can be included in the secondary system or vice versa. I

the thiclmess of the wire in the coil either. ot'these aronly the first transmitting stations, but at receiving stations the second arrangementimay be if necessary or desired.

The accompanying illustrative. drawing shows a construction of electric nductive coupling according to the invention, comprising .forexample a hollow cylindrical condenser the plates 1 and 2 of which are wound into spiral form'andare' separated from each other by a dielectric. The pole or terminal Wires 3 and 4 are adapted to be connected either in series or parallel with the current circuit or the Vibrating circuit of a system of telegraphic or telephonicap paratus. Concentric with the hollow cylindrical condenser and arrangedoutside it is a coil 5 which is adjustable in the direction of the axis of the condenser. The adjustment by which an alteration in the degree of coupling is produced maybe efi'ectedior example as shown by means of a screw spindle 7 adapted to-berotated' by a crank handle 6 and upon which is mounted an internally screw threaded fnut or sleeve, 8 that carries the coil 5. A pointer 9 con- According togdenser plate nected to the 1 sleeve indicates on a scale 7 10 the degree of coupling. The arrangement is obviously only represented byway of example and jother arrangements can likewisehe adopted: without departing from the scope of the invention. denser may be variable as a telescope-condenser or the induction coil may be an a justahle one.

It is obvions that the form or" thecondenser (plate condenser, cylindrical condensenfletc.) or the number of plates used,

or their connection as high tension or low The connec .tion too,-'mar vary according to the eiiect'to tension plates is immaterial;

be obtained. When the arrangement is used as a-conplnng device, it-is used in the Batented Nov. 3,-1 914. Divided andfthjs application filed December manner ofa transformer, the condenser heing loaded by an alternating current, and i the induction coil connected to an indicator deidcec. g, a telephone or the like; or the alternating current may pass through the induction coil While the condenser is connected with the telephone. The mode ment' is the following: The alternating current or theintermitting direct current is fed' to the condenser plates 1 and 2 and. there an electric alternating field is produced, electric lines of force passing from one conto the other and alternately of operation of the arrangcQ being produced and vanishingtnere- This Y electric field produces in'this case a cylindrical magnetic field a direction perpendicular to its own, which in its turn generates a cyclic electric field perpendicular to itselr" and therefore an induction current in the coil 5 which passes the winding of the coil and the l a aratns switched in the circuit connected to the conductors Ill and 12 which are leading from the coil. The farther the coil 5 is pushed over the condenser plates 1' and 2 by manipulation of the-crank handle and the screw spindle 7 the closer will he the coupling and the more intense will he the current in the coil until the maximum is attained in the middle position. The

pointer 9 enables. the degree of coupling to V be easily read or on the scale'll).
